The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
2. the answer is no because both the proteins of the insulin are different.
Answer:
1. B. Methane
2. C. Methane collection system
More information is required to completely answer the question. Based on the experiment, feeding one group wood only and the other wood and antibiotics, the conclusion to be drawn is that the bacteria that lives in the gut of termites does not aid in digestion of the cellulose in wood.
Antibiotics only affect bacteria and so would leave the protozoa and the archaea in the gut of the termites. Both groups received the same amount of energy at the end of the experiment so it means that digestion is aided by either the protozoa or archaea and not bacteria.
